Claim 1
Independent Claim
153 words
AN OIL-SOLUBLE, NITROGEN- AND BORON-CONTAINING COMPOSITION PREPARED BY THE PROCESS COMPRISING FORMING AN ACYLATED NITROGEN INTERMEDIATE BY THE REACTION OF ONE EQUIVALENT OF A SUBSTANTIALLY HYDROCARBON-SUBSTITUTED SUCCINIC ACID-PRODUCING COMPOUND HAVING AT LEAST ABOUT 50 ALIPHATIC CARBON ATOMS IN THE SUBSTANTIALLY HYDROCARBON SUBSTITUENT WITH AT LEAST ABOUT ONE-HALF EQUIVALENT OF A HYDROXY-HYDROCARBON AMINE HAVING THE STRUCTURAL FORMULA R-NH-R WHEREIN R IS SELECTED FROM THE CLASS CONSISTING OF HYDROGEN, INERT HYDROCARBON, HYDROXY-HYDROCARBON RADICALS, AT LEAST ONE OF THE TWO R RADICALS IN SAID FORMULA BEING A HYDROXY-HYDROCARBON RADICAL AND REACTING SAID ACYLATED NITROGEN INTERMEDIATE WITH A BORON COMPOUND SELECTED FROM THE CLASS CONSISTING OF BORON OXIDE, BORON HALIDES, BORON ACIDS, AMMONIUM SALTS OF BORN ACIDS, AND ESTERS OF BORON ACIDS IN AN AMOUNT TO PROVIDE FROM ABOUT 0.1 GRAM-ATOMIC-WEIGHT OF BORON FOR EACH MOLE OF SAID ACYLATED NITROGEN INTERMEDIATE TO ABOUT 10 GRAM-ATOMICWEIGHT OF BORON FOR EACH GRAM-ATOMIC-WEIGHT OF NITROGEN OF SAID ACYLATED NITROGEN INTERMEDIATE.
